Definitions
- the present invention relates to packaging machines and particularly to the product delivery services extending between a weigher and a former of a packaging apparatus.
- Packaging apparatus includes a weigher that delivers discreet batches of product to a chute extending to a former.
- the former receives stripped bag material and forms the bag material into a tubular configuration.
- the product is delivered to the interior of the tubular bag material, with the tube bag material being subsequently longitudinally and transversely sealed and cut to form discreet packages.
- the surfaces over which the product passes between the weigher and former include the internal surfaces of the weigher buckets, a weigher chute and further chute extending between the lower end of the weigher chute and the former.
- EP1164365 describes a combination weighing and counting apparatus that suffers from similar problems, i.e. product travelling through the hopper and its associated gates can be subject to angular velocity that may result in damage.
- a weigher bucket for a weigher of a packaging machine according to claim 1.
- This delivers product to a chute having a vertical axis, said bucket including a pair of spaced side walls between which a bottom wall extends, and over which the product passes, said bottom wall having at least one trough to control the trajectory of the product leaving the bucket to minimise angular velocity of the product about the vertical axis of the chute.
- said internal surface has a plurality of radially and axially downwardly extending troughs that engage the batches of product.
- a weigher 10 has a plurality of weighing buckets 11 that weigh batches of product and deliver the batches to an upper chute 12.
- the upper chute 12 in turn delivers the weighed batches of product to a lower chute 13 that would be located above a former of a packaging machine.
- the product is delivered to the interior of tubular bag material, with the tubular bag material being longitudinally and transversely sealed, and transversely cut to form discreet bags of the product.
- the chute 12 is frusto-conical in configuration and has an upper edge 14 and a lower edge 15.
- the chute 13 is of parabolic configuration and has an upper edge 16 and a lower edge 17.
- Each of the buckets 11 includes a fixed portion 18 with which there is associated with a movable bucket door19.
- the bucket doors 19 are pivotally mounted and are moved by actuators 20 between an open position and a closed position relative to the fixed portion 18.
- the bucket door 19 is opened to release the batch of product for delivery to a packaging machine located below the former.
- the doors 19 would be opened in sequence so as to be in phase with the operation of the packaging machine.
- Each bucket 11 includes a pair of spaced upwardly extending side walls 21 between which there extends a bottom wall 22.
- the bottom wall 22 has one or more downwardly extending troughs 23 which engage the product so as to inhibit angular movement thereof about the vertical axis X. That is, the troughs 23 engage the product to control the trajectory of the product to eliminate or at least minimise any angular velocity of the product about the vertical axis X.
- Each of the troughs 23 tapers from a maximum width adjacent the lower edge of the fixed portion 18, to a minimum width adjacent the upper rear edge 24 of the fixed portion 18. In this embodiment, each of the troughs 23 increases in depth from the rear edge 24.
- the troughs 23 may be of an arcuate configuration, "V" configuration or a “W” configuration or other configurations as shown in figure 4 . Still further, individual troughs 23 may be spaced by means of ridges 25.
- the chute 12 has an internal surface 26 provided with a plurality of downwardly extending troughs 27, which in this embodiment are aligned with the troughs 23.
- the troughs 27 do not have an angular direction of extension, that is they do not extend angularly about the axis X and therefore prevent or at least inhibit the batches of product having any angular velocity above the axis X. Accordingly, the troughs 27 are radially and axially extending. The troughs 27 therefore control the trajectory of the batches of product passing the chute 13.
- the troughs 27 may be arcuate, "V" in transverse cross-section or include a plurality of ridges.
- the chute 13 has a plurality of downwardly extending troughs 28 which are aligned with the troughs 27.
- the troughs 28 do not have an angular direction of extension about the axis X and therefore direct the product towards the lower opening 29 so as to eliminate or at least inhibit the product having any angular velocity about the axis X.
- the troughs 27 are radially and axially extending.
- the troughs 23 are aligned with the troughs 27 that are in turn aligned with the troughs 28.
- the troughs 27 prefferably be aligned with the troughs 28 on the opposite side of the axis X so that should product travel across the interior of the chute 13, the product will engage a trough 28 on the opposite side to thereby again inhibit angular movement of the product.
